C :

#include<stdio.h>
int main()
{int c,r,h,f;
scanf("%d %d",&h,&f);
c=(4*h-f)/2;
r=h-c;
printf("%d %d",c,r);
return 0;
}

C++ :

#include<iostream>
using namespace std;
int main()
{
	int head,foot,ji,tu;
	cin>>head>>foot;
	ji=(4*head-foot)/2;
	tu=head-ji;
	cout<<ji<<' '<<tu<<endl;
	return 0;
}

Pascal :

var
   head,foot,ji,tu:longint;
begin
   readln(head,foot);
   tu:=(foot-(2*head))>>1;
   ji:=((4*head)-foot)>>1;
   writeln(ji,' ',tu);
end.

Python :

# x + y = a
# 2x + 4y = b
# x + 2y = b / 2
# y = b / 2 - a
# x = a - y

a , b = raw_input().split()
a = int(a)
b = int(b)
y = (b >> 1) - a
x = a - y
print x , y
